Abstract
A discharge extension tray can be extended in a sheet discharge direction from a discharge tray. A front end regulating portion is coupled to the discharge extension tray on a downstream side in the sheet discharge direction of the discharge extension tray such that the front and regulating portion is turnable with respect to the discharge extension tray. A sheet guide portion guides a front end portion of the sheet to a direction separating from a turning center of the front end regulating portion when a sheet having a length longer than a predetermined size is discharged in a state where the discharge extension tray is not extended from the discharge tray.

An image forming apparatus for forming an image on a sheet, the image forming apparatus comprising:
- a main assembly including an image forming portion configured to form the image on the sheet;
- and
- a sheet discharge unit disposed above the main assembly, the sheet discharge unit including:
- a plurality of discharge portions including a first discharge portion and a second discharge portion disposed above the first discharge portion, configured to discharge the sheet on which the image had been formed by the image forming portion to an outside of the image forming apparatus;
- and
- a plurality of trays including a first tray on which the sheet discharged by the first discharge portion is to be stacked and a second tray on which the sheet discharged by the second discharge portion is to be stacked, the second tray being disposed above the first tray,
- wherein each of the first and second trays includes a protruding portion which protrudes from a surface thereof on which the sheet is to be stacked and which is disposed in a downstream end thereof in a discharge direction of the sheet,
- wherein when viewed in a width direction of the sheet perpendicular to the discharge direction of the sheet, the protruding portion includes an inclined surface which is inclined upward in the discharge direction of the sheet and which is inclined with respect to a vertical direction, and
- wherein the main assembly includes a cartridge in which the image forming portion is provided, and wherein the cartridge is arranged between the second discharge portion and the protruding portion of the second tray in the discharge direction of the sheet when the image forming portion forms the image on the sheet.
An image forming apparatus for forming an image on a sheet, the image forming apparatus comprising:
- a main assembly including an image forming portion configured to form the image on the sheet;
- and
- a sheet discharge unit disposed above the main assembly, the sheet discharge unit including:
- a plurality of discharge portions including a first discharge portion and a second discharge portion disposed above the first discharge portion, configured to discharge the sheet on which the image had been formed by the image forming portion to an outside of the image forming apparatus;
- and
- a plurality of trays including a first tray on which the sheet discharged by the first discharge portion is to be stacked and a second tray on which the sheet discharged by the second discharge portion is to be stacked, the second tray being disposed above the first tray,
- wherein each of the first and second trays includes a protruding portion which protrudes from a surface thereof on which the sheet is to be stacked and which is disposed in a downstream end thereof in a discharge direction of the sheet,
- wherein when viewed in a width direction of the sheet perpendicular to the discharge direction of the sheet, the protruding portion includes an inclined surface which is inclined upward in the discharge direction of the sheet and which is inclined with respect to a vertical direction, and
- wherein the main assembly includes a laser scanner above the image forming portion, and wherein the laser scanner is arranged between the second discharge portion and the protruding portion of the second tray in the discharge direction of the sheet.
